Lincoln Continental Dome Light Bulb Size

Additional Notes

• The Lincoln Continental dome light specifications span from 1958 to 2002, with eight distinct bulb types used across that period: the 214-2, 211-2, 912, 1003, 105, 194, 631, and 89.
• The 211-2 and 214-2 are both festoon bulbs sharing the same 41mm length, SV8.5 base, 12V rating, and 12W output. Despite their near-identical specifications, they are catalogued as separate part numbers and are not listed interchangeably in these fitment records.
• The Lincoln Continental (1998-2002) uses the 214-2 festoon bulb, while the 1988-1994 and 1975-1977 model years use the 211-2. Both types share the festoon form factor, which seats into spring-clip holders at each end rather than using a base socket.
• The 912 wedge bulb is specified for the 1980-1987 model years. It is a T15 wedge type and a variant of the 921, operating at 12V and 12W. Wedge bulbs use no separate base, as the glass envelope itself forms the contact points.
• The 1003 bayonet bulb appears across several non-consecutive model years: 1958-1960, 1972, and 1978-1979. It uses a BA15s single-contact bayonet base and draws 21W, making it the highest-wattage bulb in these specifications.
• The 631 bulb is specified for the 1963-1968 model years. It is a single-filament BA15s bayonet type and a variant of the 1156, rated at 12V and 21W, matching the 1003 in wattage despite being a different part number.
• The 105 bulb is listed for the 1969-1970 and 1974 model years. Like the 631, it is a BA15s bayonet variant of the 1156, but it draws only 13W rather than 21W, placing it in a lower output class within the same base family.
• The 89 bulb is specified solely for the 1961-1962 model years. It also uses a BA15s bayonet base and is described as a lower-wattage variant of the 1156, rated at 13W, the same output as the 105.
• The 194 miniature wedge bulb appears only in the 1971 model year. At 3.78W, it operates at a substantially lower wattage than every other bulb type in these specifications, and its T10 wedge form factor is distinct from the T15 wedge of the 912.
• Several bulb types in these specifications share the BA15s bayonet base, including the 1003, 105, 631, and 89. Despite this shared base type, their wattage ratings differ, and substituting one for another would alter the light output of the dome lamp.
